Description

Air purifier for treating waste gas generated in fore-spinning process

Technical Field

The utility model belongs to the environmental protection field, more specifically say, relate to an air purifier for spinning waste gas before handling.

Background

A great amount of harmful gas can be generated in the production process of a nylon spinning factory, and pollutants such as polyamide oligomer, emulsified oil mist and the like exist in the air. The high temperatures generated during the production process by screw extrusion lead to the polyamide oligomers precipitating out and evaporating into the surrounding air. In addition, the spinning production process requires that the filament bundles must be heated and drawn, and the heating and drawing of the filament bundles can cause the emulsified oil agent to volatilize, and finally oil mist is formed. Therefore, the production workshop of the nylon spinning factory usually has certain pungent smell, and simultaneously has oil mist with gray covering and a small amount of smoke dust. If the polluted gas is not treated, on one hand, the polluted gas can cause damage to the physical health of workers in a workshop, and on the other hand, certain threats can be caused to the health and the natural environment of surrounding residents. Therefore, it is necessary to purify the gas in the plant.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: an air purifier for treating waste gas generated by fore-spinning comprises a tank body, a group of spray heads, an air equalizing plate and a water baffle plate; the tank body is cylindrical and is vertically arranged, the side wall of the tank body is provided with an air inlet, the top of the tank body is provided with an air outlet, and the bottom of the tank body is provided with a water outlet; the air equalizing plate is horizontally arranged in the tank body and is positioned above the air inlet; the water baffle is horizontally arranged in the tank body, is positioned below the air outlet and is positioned above the air equalizing plate; the side wall of the tank body is provided with a group of spray heads in inward directions, and the spray heads are all positioned between the air equalizing plate and the water baffle plate.

The purification process of the air purifier for treating the exhaust gas from the fore-spinning process is as follows. The spray head sprays water into the tank body, water mist is formed between the air equalizing plate and the water baffle plate, and the water mist slowly moves downwards under the action of gravity. Meanwhile, air supply equipment such as a blower is used for introducing the waste gas into the tank body from the air inlet, the waste gas flows from bottom to top in the tank body, and the waste gas flows smoothly and stably after flowing through the air equalizing plate. The exhaust gas continues to flow upwards and is mixed with the water mist. The particles in the waste gas are gradually gathered under the scouring action of the water mist and fall along with the water mist, and the harmful substances in the waste gas are absorbed into the water mist through repeated exchange with the fog drops and fall along with the water mist. The purified gas flows through the water baffle plate, and is discharged after a part of water is removed. The falling water mist is finally collected to the bottom of the tank body and is discharged from the water outlet. Wherein, the wind-equalizing plate and the water baffle plate can be corrugated plates or perforated plates.

Further, in the air purifier for treating waste gas from fore spinning, the air passage is sequentially connected from bottom to top by the air inlet section, the rectifying section, the contraction section, the diffusion section, the water inlet section, the mixing chamber and the nozzle; the air inlet section is positioned in the seat body and vertically penetrates through the seat body, the nozzle is positioned at the top of the protruding part, and the water inlet hole is arranged in the water inlet section. The air inlet section is used for being connected with external compressed air, and compressed air collides with water flowing in from the water inlet when flowing into the water inlet section and is primarily mixed, and then enters the mixing chamber for further mixing and then is sprayed out from the nozzle.

Further, in the air purifier for treating exhaust gas from fore-spinning, the water inlet holes comprise a group of first water inlet holes and a group of second water inlet holes; the included angle between the water inlet direction of the first water inlet hole and the advancing direction of the air passage is more than 90 degrees; the included angle between the water inlet direction of the second water inlet hole and the advancing direction of the air passage is less than 90 degrees; the first water inlet hole and the second water inlet hole are distributed in an annular array. The first water inlet hole and the second water inlet hole have different included angles, so that the mixing state of the first water inlet hole and the second water inlet hole is different when the first water inlet hole and the second water inlet hole are contacted with the airflow; the included angle between the water flow direction in the first water inlet hole and the air flow direction is larger than 90 degrees, the water flow collides with the front side of the air flow, the atomization effect is good, but the energy loss is large; the included angle between the second water inlet hole and the first water inlet hole is different and can be complementary with the first water inlet hole; in addition, the density distribution formed in the radial direction of the air flow is different after the water flow in the first water inlet hole and the second water inlet hole is impacted by the air flow, so that the first water inlet hole and the second water inlet hole are matched for use, and the mixing is more uniform.

The distribution and flow rate of the water mist are different along the radial direction in the tank body. Considering that the spraying capability and flow rate of the spray head are limited, when the diameter of the tank is too large, the above-mentioned radial distribution becomes more significant, which may result in a reduction in the efficiency of water utilization. In order to adapt to the tank body with the large diameter, the occupying column can be arranged in the tank body and occupies the central area of the tank body, so that the radial unevenness can be reduced, the relative flow rate of the waste gas and the water mist can be increased, the utilization efficiency of water is increased, and the purification effect of the waste gas is improved.
